HYDROCARBON-MOTOE.

Specification of Letters Patent.

Patented Feb. 10,1914..

Original application led July 26, 1909, Serial No. 509,594. Divided andthis application led July 25,

1913. Serial No. 781,190.

To all whom t may concern Beit known that I, RUSSELL HUFF, a citizen ofthe United States, and resident of Detroit, in the county of Wayne andState of Michigan have invented certain new and useful Improvements inHydrocarbon- Motors, of which the following is a specification. y

This application is a division of application Serial No. 509,594, ledJuly 26, 1909,

and .the invention relates to hydrocarbon motors of the sleeve valvetype. e

One of the objects of the present invention is to arrange the valvesleeves so that the-y are free from the side thrust of the pistons.

Another object of the invention is to provide an annular valve chamberthat is closed at both ends and is entirely separate from the combustionspace of the" motor except through the inlet and exhaust ports which arecontrolled by the valve sleeve or sleeves within the chamber.

Another object of the invention is to so constructa motor of the sleevevalve type that the inner and outer members that form the annular valvechambers will-have no joints throughout the parts on which the valvesleeves slide and with the joints between these members located at theupper ind lower ends of the respective valve chamers.

Another object of the invention is to so construct a motor of the sleevevalve type that the spark plugs or 'other ignition devices and the waterconnections for the head may be located in the top of the head in anaccessible position, While at the same time the head and the surroundingcasing, between which the annular Valve chamber is formed, may bevsuitably connected to close the upper end of the valve chamber.

Another object of the invention is to make the parts forming the valvechambers readily detachable to facilitate machining and to make thevalves easily accessible.

Other objects will appear from the following description taken inconnection with the drawings, which form a part of the specification,and in which,

Figure 1 is a vertical sectional view of a motor embodying thisinvention, being taken on the line 1-1 of Fig. 2; and Fig. 2 is asection on the line 2-2 of Fig. 1, with parts shown in plan.

and 11, and it is closed at its upper end by means connecting theadjacent upper ends of said members 10 and 11. This connecting means maybe of any suitable form so .that it does not extend entirely over thetop of the inner member, and it is shown in the form of an annular lange14 which fits the `topi of the outer member and is secured, as by screws15 and a ring 16, to the upper end of the inner member. A ring 17engages the upper side of the ange 14 and is clamped,

against the flange and removably secured to the upper end of the member10 as by bolts 18. The flange 14 thus forms a closure for the top of thevalve chamber 12 and the inner and outer members are readily detachable.

The upper part of the inner member 11 forms the head of the cylinder,having a transverse water-cooled part 19 which performs this function.By reason of the fact that the connecting means between the upper endsof the members does not cover the part 19 of the inner member, the sparkplug or other ignition device 20 may be arranged in the center of thepart 19 and a water connection 21 may also be mounted in this part. Thusboth the spark plug and the water connection are accessible through thering 17 and its cooperating connecting members. The spark plug is thusarranged approximately in the center of the combustion space 22 of themotor where it is most effective and the water is taken from the`extreme upper end of the, inner member so` that no air pockets inthe'water acket are possible. vThe inner member 11 is formed with inletvand outlet ports 23 which communicate with the combustion space 22 andwith the valve chamber 12 substantially midway between the ends of thelatter, and the outer member 10 has ports 24 which also communicate withthe valve chamber 12 and, are alined with the ports 23. As shown, thereis a circulation of water around the ports 23 through ducts 25 in theconnection 26 formed between the parts of the inner member 11 which areabove and below the ports 23. llt will be understood that the walls ofthe valve chamber 1,2 are accurately machined and ground and if desiredsuitable packing rings 27 and 28 may be employed for the purpose of moreperfectly closing the ports in the valve sleeve about to be described.

One or more valve sleeves `may be arranged within the valve chamber 12for the purpose of coperating with the prts 23 and 24 in the inner andouter members respectively, and inl the drawings two such sleeves, 29and 30, are shown. These sleeves are respectively provided with ports 31and 32 which coperatie with the ports 23 and 24 as above suggested, forthe purpose of opening and closing these ports to operate the motor onthe four stroke cycle.

The cylinder of the motor may be suitably arranged below the valvechamber forming members 1() and 11, and in the present instance thecylinder 33, in which the piston 34 slides, is formed as an integralpart of the inner member 11, being suitably waterjacketed, as at Thewhole of the motor as above described is mounted upon a suitable crankcase 36, the upper part only of which is shown in the drawings, anddiagrammatically illustrated are the connecting V rod 37 and crank shaft38, which latter is of course mounted in the crank case.

The valve sleeves 29 and 30 may be arranged to slide in any suitablymanner upon their respective ground surfaces, and in the drawings theinner valve sleeve is operated by means of a sliding rod 39 connected toan eccentric 40 by means of a connecting rod 41. The outer valve sleeveis provided with an extension 42 which is connected to a rod 43 by meansof the reinforcing piece 44. The rod 43 is operated from an eccentric 45by means of a connecting rod. 46. The eccentrics and 45 are mounted uponthe eccentric shafts 46 which are driven from the crank shaft by meansof the usual two-to-one gearing 47.

It is believed that the operation of the valve sleeve in the embodimentof the invention shown will be obvious, it being understood thatfin -thedrawing the piston and the other working parts are shown in the upperdead center position of the exhaust stroke and the ports in the sleevesand in the inner and outer members will coperate at the proper times forthe operation of the motor on the four stroke cycle. It will be seenthat the valve sleeves are so arranged that they are not subjected tothe side thrust of the pistons, and being located in carefully closedchambers, the walls of which are unbroken save for the ports and rings,and

which are closed above and below the valve sleeves, leakage along thesurfaces of the valves will be reduced to a minimum.

lt will be understood that suitable means for feeding oil tothe abovesleeves may be provided as in the motors sh'own in said application,Serial No. 509,594, and, if desired, other features of said motors maybe adopted in cooperation with thc motor shown in this application. Forinstance, while l have shown the sleeve operating mechanism as mountedbelow the cylinder, it will be obvious that other operating mechanismmay be employed and if desired located above the cylinder, as shown insaid application. It is also to be understood that this invention is notto be limited to a plurality of superposed valve sleeves for eachcylinder, since an engine of this type may be operated with a singlesleeve or with a plurality of sleeves which are not superposed. It isfurther o bvious that various changes may be made in the details ofconstruction without departing from the spirit of this invention, and itis, therefore, to be understood that this 1nvention is not to be limitedto the specific construction shown and described.
